The way I feel about it is that if it's a lemon, be it AK, AR, Dodge, or anything else I'm going to get rid of it. The only way you begin or build trust in your weapon, vehicle, woman or anything else is through consistent use. If it's not being consistently used and a person trusts it anyway I think they are making a huge mistake.
I think that applies to any gear you have. I've got a buddy who has an LBV all set up that I suspect has never made it out of the closet. (I've never seen him wear it.) How does he know for sure that the vest or the way he has it set up is going to actually work for him? In my opinion he doesn't. But he's bragged on it a couple of times anyway.
He's also got a pair of black combat boots that are as new as the day he got them. I think he's asking for trouble.
